Firefox and chrome app upgrade on OSX

I just recently cut a XUL/Chrome development environment from
Firefox 0.7 to the most recent build of Firefox (1.0+). I
moved the application into the chrome directory and edited the
installed-chrome.txt file as I had it in my 0.7 build.

Nothing happens when I use -chrome//MyApp/content/ in the URL.
It seems to find the file (or at least does not complain about not
finding it), but just sits there ---

That said, I don't know what file to look at to make sure the
app got loaded (it used to be something like chromelist.rdf?).

Are there any docs out there to tell me about what seems to be
the difference in chrome installations, say differences that
occurred over the past 2-3 months?

Thanks
